I started installing Leopard last night before going out. I came back late last night (or early this morning) and sat down to explore the new OS. There was a pop-up about using Time Machine with my external hard drive. I clicked okay. It began loading and running Time Machine before telling me my external hard drive was the wrong format or something. It then gave me the option to delete (which I assumed ment delete the Time Machine files from my external hard drive). I clicked on it. A few minutes later I realized that it had erased my entire external hard drive, renaming it "Time Machine Backups". I had JUST moved my entire music and movie collection to that hard drive and am wondering if there's any way I can recover those files. (The irony of having my back up files deleted by Time Machine makes this whole situation extra painful) Any help will be appreciated. I really want those files back.
